In today's digital world, our smartphones have become an integral part of our lives. We store sensitive information, use banking apps, and access confidential data on these devices. While Android offers robust security features, it's crucial to safeguard our privacy and prevent unauthorized access to sensitive apps. This article will guide you through the best methods to lock apps on your Android device, ensuring your data remains secure.
Understanding the Importance of App Locking
